I'm just lazy Mick and congrats on your post pushing the thread to 100 pages.

We had mixed results at the track during test and tune.
The motor found a lot more grunt low down and brought the 60 foot down by a couple of tenths with a series of 2.1## runs but the weather caused the bike to go real rich and nobbled the top end performance.
Despite this the numbers it turned were quite consistent which is what the bike was designed to do.
The motor was winding up against the brake to 3000rpm but the rear brake could not hold the power and it literally pushed the bike forward with the front brake completely locked on.

For Jon Weeks, I asked about the line lock in S ET and it's OK. I guess this is the way we will have to go. will phone you shortly.
For Frank (Dragracer) ring us on Billys cell number.

Sam.

Nobbled??? Do you mean hobbled or is that just more Panama boom boom sailor bar talk.

Good to read you are at 3,000 stall....if it is rich note the RPM and either drop the needle , reduce the main or both. Good luck guys and I'll talk to you tonight.

Sam hasn't posted today's results yet. There was an accident at the track where a nitro harley motor blew up on the burnout. The shrapnel from it struck multiple people, causing some serious injuries. It puts into perspective the dangers of following the desires to go racing. Sam and Team Green are fine. The bike needs more back wheel braking to hold the new found midrange power. Plans have been made to resolve that issue before the November Manufacturer's Cup meet. A sad day for motorcycle drag racing.

Pack it in you two, this is serious

we are in this very expensive posh hotel suite and Billy has my carbs on the table swapping out the jets and altering the needles

After the last two weeks testing at Atlanta Dragway and on the Paul Livengood dinomometer, the bike looked to have made some good progress in the right direction.
It was found that the current set up was allowing the converter to spin up from the former 2,600 rpms to 3,000rpm which would help the launch. unfortunately at 3,000 revs, there is know no way that the rear brake would hold it on the line so we are going to have to do what we were told a long time ago by our crew chief and go to a line lock.
We tried a stock converter to see if it would help, it eased things a little but still required some throttle hold back to stop it pushing the bike into the staging beams and red lighting.
In the eliminations, trying to juggle the revs, brakes and watching the revs as well proved a little to much for me and although the bike did just the opposite to what it should have done, in the end I red lighted and put myself out.

We'll have another go tomorrow but I doubt it will be any more manageable so until the line lock is fitted, It's keep your fingers crossed for us time.

Sam.

PS, thanks for that Jon, posted just before I could.

Hi People, Jimmy had to leave early to be fresh for work on Monday morning so tonight, Sam is Billy CowBell

We all had a great time but no wins again.
The only round wins went to Pops911 Richard who went several rounds on his 400 Hondamatic twin the Turtle. If you have ever taken notice of Richards posting, you will know that he has no respect for anyone, It don't matter who you are, how good you are or how fast your bike is, mess with Richard like a guy on an 8 second bike tried to do and you'll go home with egg on your face

Richard eventually went out to a red light as did lots of people, most thought that they had not red lighted and said they thought that the timing system was set up real tight to what they normally are.

Although we are still learning how to ride these bikes, we both, Billy and myself managed several personal bests at the different increaments of the track.
We both managed PBs on the 60 foot with 2.1s but today, Billy took Calendar Girl to a 1.863 record and then the 8th mile with a 7.78 time and backed it up with several more in the high 7s.

But the biggest shock was when I took the automatic to a fantastic 130mph terminal speed with 13,500 rpms showing on the clock. This was no joke but you'll have to wait for the details as we are due to leave for dinner.

Sam.

Sam typed about 30 minutes and hit the wrong button!

now he's hit z bed! ;)Oh well,it's his story,but he did hit 130......in the 3/8!

Jim French,thanks so much,we couldn't have done it w/out you!

He crossed the line @ 114.96.....and then he hit z button!he said bike revved to 13,500 and took off like you hit the NOS!
I think it was` a 12.8xx run.2.1 60 ft. 93.xx 1/8 mile.
Calendar Girl ran a 12.252 against a 12.30 dial in.Ran one of Rickey's bikes(rider from Japan),yes I looked back,yes I sat up,yes I scrubbed 12 mph off run,and yes I chopped throttle and COASTED across line,and yes still broke out,no doubt it would have been in the 11's!!!!!!!!!!!!!

More tomorrow. Bill

Good to see the crew together again. I didn't get to spend as much time with you fellas as i had planned. I had what now seems to be electrical issues with the new 8.88 bike that i couldn't get sorted out but i did make a round in Pro ET on the dragbike that Curtis Grigs and i built a few years ago. The original engine broke the crank at the end of last season so i put a smaller backup motor on it just to make this race. I had no baseline on the launch rpm for the 2 step or an ET projection. On top of that the delay box failed before the first time run and i had to bottom bulb race. Hard to make rounds in Pro ET without the proper electronics. We got called to the lanes for the one and only time run for saturday before eliminations started. I took a chance and set the launch rev limiter at 7500. The bike bogged off the line on the 1st time run and only ran a 10.20. Since the 10.20 ET it wasn't a representative pass, i took a chance for first round eliminations and dialed a 9.80. My opponent dialed a 9.40 on his ZX10 street bike. I left the line first and looked back at half track. My opponent was no where in site so i figured he either had problems off the line, i had cut a much better light or i was on a breakout pass. I started to roll out of the throttle a bit but figured it best to chop throttle completely and look back again. He was still not close but the finish line was coming up fast. I grabbed the front and rear brake thinking i had scrubbed off enough ET to keep from breaking out. He passed me after i crossed the line but as i looked for the win light on the concrete wall, it lite up on his side- not mine. Damn, musta broke anyway. Sure enough when i looked at the ticket at the ET shack, i had run a 9.71 @ 105 mph on my 9.80 dial in. Crap, now i had to take an educated guess on what the ET would have been in the 1/4 mile based on my 1/8 ET of 5.85 and mph. I bought back in but this time lowered my ET to a 9.40. Just my luck but i paired up in 2nd round with my buddy Wade from NC. We had a long time friendly rivalry so i knew i had to chop his head off to win bragging rights. He dialed a 8.10 ET so i left first. I knew i had messed up on my reaction time but by the time we got to the stripe, he flew past but my win light came on. He redlighted and i got the win. His reaction time was a -115, mine was a .115. Next round i left my dial in at 9.40. Since i slept the tree the previous round i knew i had to tighten up my reaction since my opponent had a delay box. Light came down and i dropped the clutch lever only to see a freakin red eye staring at me. At the ticket booth my reaction time was a -014 and i ran a 9.41 on my 9.40 dial in. Oh well. I had fun. I was approached by a friend about riding his top gas bike in eliminations on sunday. We set about prepping the bike for the final time run of the day but found problems with the brakes and the two step. His mechanic was there to fix the problems but he didn't get done in time to make the last qualifying run of the day. We were told they would still place us on the ladder for sundays eliminations.

I didn't buy a tech card for PRo Et on sunday since we iintended to run top gas. I checked the eliminations ladder on sunday morning but my name was not one the list. Long story short, the track officials didn't want to add us to the list eventhough the Cup race directors told him it was ok. To avoid confusion i told them to refund out entry fees and we would just race another day.

I served as pit crew all day sunday for the guys i knew and enjoyed the day even if i wasn't racing myself.

Had fun chatting with Sam. Jim and Bill this weekend. Got to see some of the runs for both of the Honda's. Looking forward to coming to Commerce to race with Bill and Jim in the future months.

STAGING LIGHTS ? : They are set on the ground fixed in place and no COMPULINK SYSTEM changes the reaction lights times. After 4 rounds my lights were .020 - .062 - .092 - .033 and then a .006 red light you don't win rounds in OHIO with 3.43 reaction times. I treed every rider in every race and ran .09 off my dial in and covered every racer off the line until the .003 red light. After 4 rounds there was still 25 racers in ST/ET because of the buy backs in rounds 1 and 2 losers. That would make for a 11 rounds win to get the last win. I raced 8 rounds before and won but even JOHN FORCE could not win much going 11 rounds. Great track and weather but I will stay up NORTH as I watched bikes with NO KILL LANDYARDS, NO REAR BRAKES, and a guy racing a 9 second bike with a CLOTH BATES COAT, Craftman cloth gloves and no kill landyard. This is the guy who will hit the front brake when he is trying not to breakout against THE TURTLE [ ME ] flip the bike and cross over in my lane with a running bike for me to crash into in my lane = like I'M dumb. I'll stay at a NHRA run rules track to keep my retirement check !!!!!!
I done tech at AHDRA and IDBA many times over the years and there is a few simple rules that every bike and rider should have to follow or is it a STREET RACE at a track

Seen lots of those street races and even them folks wore leathers. Good luck folks IDBA was in court for 20 years over a death at a track because the bike was to low and stuck in the track with a flip over = remember the 2 inch rule you have to pass over in TECH !!!!!

Billy, if the throttel stuck, the motor would keep building speed at the same rate, why did it kick me up the arse like an exorcett missile had run into the back of me when I closed the throttel. ?

Cause @ WFO you were still slipping(T/Q)?,when you backed off,it was enough for T/Q to sense load difference and lock up completely! You backed off @ line,it didn't! It went to 7/8 throttle @ 115mph and now WASN"T slipping @ all,so off ya'll went to 130 mph in 3/8!

.That's my story and I'm sticking to it,hung up on carb clamp,got rid of OEM clamps cause of the lip on 2&3 was too close....guess it still is

,It won't be!!!!!!
